Usage & Applications of Angle Steel

According to the needs of different structures, Angle can compose to different force support component, and also can be the connections between components. It is widely used in various building structures and engineering structures such as roof beams, bridges, transmission towers, hoisting machinery and transport machinery, ships, industrial furnaces, reaction tower, container frame and warehouse etc.

Packaging & Delivery of Angle Steel

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.

Q: How do steel angles perform under seismic loads?: Steel angles perform well under seismic loads due to their inherent structural properties. The L-shape of steel angles provides excellent resistance to bending and torsion forces, making them ideal for withstanding the lateral forces generated during earthquakes. Additionally, their high strength-to-weight ratio and ductility allow them to absorb and dissipate seismic energy effectively, minimizing the potential for structural failure and ensuring the safety of the building.

Q: Can steel angles be used for framing in modular construction?: Yes, steel angles can be used for framing in modular construction. Steel angles are commonly used for their structural strength and versatility, making them suitable for various framing applications in modular construction projects.

Q: Can steel angles be used for framing or supporting suspended ceilings?: Yes, steel angles can be used for framing or supporting suspended ceilings. Steel angles provide excellent structural support and can be easily attached to the walls or ceiling to create a sturdy framework for suspended ceilings. They are commonly used in construction and are known for their strength and durability, making them suitable for this purpose.

Q: What are the different methods of surface finishing for steel angles?: Steel angles can be finished using various methods, each with its own advantages and considerations. Painting, galvanizing, powder coating, and shot blasting are the most commonly used methods. When it comes to surface finishing steel angles, painting is a popular choice. It not only protects against corrosion but also adds an appealing look. Typically, the angle is cleaned and primed before multiple coats of paint are applied. This method allows for a wide range of colors and easy touch-ups in case of damage. Galvanizing, on the other hand, involves coating the steel angle with zinc to safeguard it from corrosion. This method is particularly effective in harsh environments where moisture or chemicals may be present. The most common technique is hot-dip galvanizing, wherein the angle is immersed in molten zinc. This creates a durable finish that requires minimal maintenance. Another widely used method is powder coating, which entails applying a dry powder to the angle and then curing it with heat. This forms a protective layer that offers excellent durability and resistance to corrosion, chemicals, and UV rays. Powder coating also provides a smooth and consistent finish, with a wide array of color options. For a mechanical surface finishing approach, shot blasting is employed. This method involves blasting the steel angle with high-speed abrasive particles to remove rust, mill scale, or other contaminants. It results in a clean and smooth finish while creating a rough texture that enhances paint adhesion. Shot blasting is often used as a pre-treatment before painting or powder coating. When selecting a surface finishing method for steel angles, it is crucial to consider the specific requirements of their application. Factors such as the environment, expected lifespan, aesthetic preferences, and budget should all be taken into account. Seeking guidance from professionals or the steel manufacturer can help determine the most suitable surface finishing method for steel angles in a given situation.

Q: How do you calculate the bending moment of a loaded steel angle?: To calculate the bending moment of a loaded steel angle, you need to consider the applied load, the moment arm, and the cross-sectional properties of the angle. First, determine the applied load acting on the steel angle. This could be a point load or a distributed load, depending on the specific situation. Next, locate the point of application of the load and determine the moment arm. The moment arm is the perpendicular distance between the point of application of the load and the axis of rotation. Once you have the applied load and the moment arm, you can calculate the bending moment using the formula: Bending Moment = Applied Load x Moment Arm Finally, you need to consider the cross-sectional properties of the steel angle. These include the area moment of inertia (I) and the section modulus (Z). The area moment of inertia measures the resistance to bending and depends on the shape and dimensions of the angle. The section modulus represents the strength of the section and is calculated as the ratio of the area moment of inertia to the distance from the centroid to the extreme fiber. By using the appropriate equations and considering the cross-sectional properties, you can determine the bending moment capacity of the loaded steel angle and assess its structural integrity under the given load conditions.

Q: What are the different welding methods used for steel angles?: There are several different welding methods commonly used for steel angles, including Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), Flux-Cored Arc Welding (FCAW), and Gas Tungsten Arc Welding (GTAW). Each method has its own advantages and suitability for specific applications, but all are capable of effectively joining steel angles and providing strong, durable welds.

Q: What are the different types of steel angles connections for trusses?: For trusses, there exists a variety of steel angle connections, each with its own advantages and applications. 1. Bolted Connections: These connections, widely used for trusses, involve joining the steel angles together using bolts. They offer a secure and robust connection, while also being easy to install and disassemble if necessary. Bolted connections are often employed in situations where trusses need to be transported or assembled on-site with convenience. 2. Welded Connections: This type of connection involves fusing the steel angles together using heat and pressure, resulting in a permanent and strong connection. Welded connections are particularly suitable for heavy-duty truss applications, offering excellent load-bearing capacity. They are commonly utilized in structures that require high strength and rigidity. 3. Gusset Plate Connections: In this method, a gusset plate, made of steel, is employed to connect the steel angles together. The gusset plate is usually bolted or welded to the steel angles, providing a secure connection. This type of connection is commonly utilized when the angles need to be connected at angles other than 90 degrees. 4. Clip Connections: Clip connections utilize metal clips to join the steel angles together. These clips are typically bolted or welded to the steel angles, creating a strong and secure connection. Clip connections are often used for trusses that require a flush connection at a 90-degree angle. 5. Cleat Connections: Cleat connections involve the use of a metal plate, called a cleat, to connect the steel angles together. The cleat is typically bolted or welded to the steel angles, providing a sturdy connection. Cleat connections are commonly used for trusses that require additional reinforcement and a 90-degree angle connection. In conclusion, the selection of a steel angle connection for trusses depends on the specific requirements of the structure, such as load-bearing capacity, ease of installation, and desired strength and rigidity. To determine the most suitable connection type for a particular application, it is recommended to consult with a structural engineer or truss manufacturer.
